Marc Moskowitz claimed in court papers that managers at the Bally Total Fitness gym on E. 55th St. were aware that gay "cruising and lewd behavior" is "commonplace at the steam room, sauna and locker rooms."

"As a result of the aforementioned activities, there was bodily fluids and other evidence of sexual activity wherever it occurred throughout the gym," according to Moskowitz's suit in Manhattan Supreme Court.

Instead of having staffers clean the areas, Bally simply "left a hose and liquid soap" for people to clean up themselves, the papers state.

As a result, Moskowitz claims, he took a tumble last August and needed surgery to repair his shoulder.

Moskowitz goes on to claim that "the act of searching for homosexual partners in public places ... is prevalent at Bally's across the country."
